Some Tomcat JSP Performance Numbers
I thought it might be interesting to contribute some quickly taken JSP
performance figures for tomcat.
The numbers were not taken especially for the list, so the setting might
look a little strange.
All Measurements were short-time, typically running app. 2 minutes. I used
a very simple JSP, with a page directive setting session to false, then a
configurable sleep and then just writing out a stupid HTML-Page of varying
length.
I varied the number of simulated client threads (concurrent requests), size
of JSP output, number of server CPUs an finally I put apache and tomcat on
seperate servers.
Configuration
Apache 1.3.14, Tomcat 3.2.2-beta2, AJP13, Solaris 2.6, JDK 1.2.1_03
HTTP-client simulation on another system, simulating 100 clients (differing
numbers are mentioned),
100Mbit switched Ethernet between the systems,
Plattform webserver and client simulator seperate Sun E420R 4CPU/4GB, 400MHz
Apache andTomcat running on the same system, last two szenarios I put them
on different servers,
Tuning
Apache uses max 256 Processes, AJP13-Pool max 256 Threads
TCP/IP close_wait_interval 30 Sec
Tests
variable Output Size, no Sleep
Size Used Bandwidth Performance
25Bytes - 430 JSP/sec
1KB - >400 JSP/sec
4KB 2MBit/16MBit 415 JSP/sec
16KB 2MBit/44MBit 310 JSP/sec
variable Sleeps, 1KB Size of Output
Sleep Performance
0ms >400 JSP/sec
100ms 360 JSP/sec
400ms 185 JSP/sec
1600ms 60 JSP/sec
variable Number of Client-Threads, no Sleep, 25 Bytes Size of Output
Clients Performance
200 330 JSP/sec
175 360 JSP/sec
150 380 JSP/sec
125 405 JSP/sec
100 415 JSP/sec
75 435 JSP/sec
50 380 JSP/sec
25 225 JSP/sec
variable Number of CPUs, no Sleep, 25 Bytes Size of Output
CPUs Performance
4 430 JSP/sec
3 395 JSP/sec
2 320 JSP/sec
1 195 JSP/sec
And now two measurements with apache, tomcat and the client simulation
running on three different systems of the above type:
no Sleep, 25 Bytes Size of Output
Clients Performance
100 530 JSP/sec
200 370 JSP/sec
Again seperated, but variable Number of CPUs, no Sleep, 25 Bytes Size of Output
CPUs Performance
4 500 JSP/sec
2 510 JSP/sec
1 415 JSP/sec

Something to strive for...
If someone would like to generate stats for Velocity, that would be great!
